A man who tested positive for Covid-19 nearly a week after leaving managed isolation is believed to have had an unusually long incubation of the virus.
He returned from India on 27 August and tested positive for the virus nearly a week after leaving managed isolation.
The Auckland man's wife and child have also tested positive. All are now in quarantine.
The Director-General of Health Ashley Bloomfield says this case is not connected to the main Auckland cluster.
He told RNZ reporter Charlotte Cook a charter flight back to Auckland, with 87 people who had completed isolation, including the family is one of the places the man could have picked up the virus.
